Tn_cuple,
Same as CanadianCouple, we've never used viagra (yet), nor have we ever swung with others who have used it during playtime with us. But we've heard and known of others who do/did use it while swinging, and they (both male & females) love it!
I guess it all depends with whom you're playing with, and I suggest bringing up this subject with potential swinging partners to see how they feel about it, and if it's okay to use it during your playtime sessions with them, since everyone has their own "preferrences" when it cums to swinging.

Personally, if any of our male playmates needed that "extra" boost, I wouldn't mind if they use viagra, as long as they "give" as much as receive too. Although nothing can beat that ole "natural" sexual high...
Again, to each's own...
